Filed: 1993-07-06
Abstract: PURPOSE:To provide a method for fusing glass material in which the problem of high temperature corrosion of the compositional members and the problem of restriction on the operating temperature being set by the heat resistant temperature of the compositional members are solved simultaneously. CONSTITUTION:An object 16 to be fused (radioactive waste liquid + glass material) is thrown into a cold crucible induction fusion system 10 and a conductor having melting point higher than that of the glass material is inserted into a fusion furnace 12.
